FENCE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 407,329, dated July 23, 1889. Application filed May 2, 1889. Serial No. 309,367. (No model.)

To all 1072 0711 it may concern.-

Be it known that I, CHARLES \V. BUSH, a citizen of the United States, residing at Selden, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Fence-Makin g Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in fence-making machines; and it consists in the peculiar combinations, and in the construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a perspective view of my improvement in operation. Fig. 2 is a cross-section through the line x 00 of- Fig. 1. Fig. 3 is a section on the line y 3 of Fig. 1.

Referring now to the details ofthe drawings by letter, A designates a post, to which the wires are attached. 1% represents the wires, and C the pickets.

The mechanism for twisting the wires is mounted on a board D, the number of twisters depending upon the number of strands to the fence. In the present instance three are shown.

E E are castings secured to the board D, upon opposite sides thereof, by means of suit able fastenings, as the bolts or rivets a. These castings are formed with straight sides I), which are flush with one edge of the board, and the opposite sides are formed semicircular,as shown at c, and extend beyond the edge of the board, and are formed with lugs or flanges (1, extending toward each other, as shown, to provide guides for the rack-bar, hereinafter described, and prevent the displacement of the same. These castings are provided each with an opening 6, in which the walls of the openings 6 in the castings and are guided thereby. Slots are formed in the board and the castings, and the twisters are provided with slots upon diametrically-opposite sides thereof, as shown.

G is a rack-bar moving parallel with the board D and engaging the teeth of the twisters. It is held in contact with the twisters and guided in its movement by being held between the semicircular portion' of the castings, and embraced upon the edge by the flanges or lugs (Z of said castings. This rackbar is provided with ahandle ll, extending at right angles to the handle of the bar, as shown, and secured thereto in any suitable manner. This handle has a projection 71 which extends over the board D and moves thereon.

I I are stop-blocks on the board D, and these blocks are adjustable lengthwise of the said board by means of the elongated slots Z and bolts m, working therein. One of these blocks carries a locking-spring J, held at one end by means of the bolt that secures the block to the board, and the free end of this spring is designed to engage the projection h on the handle, as shown, the said projection being forced under said spring as the handle is moved to operate the twisters in twisting the wires;

It will be seen that by the above-described construction and arrangement of parts the operator does not have to reach through the wires every time he places a picket in the wires. I do away with the segmental gear and bevel-pinions and crank. There are no operating parts in the way of moving past a post or brace upon the post. The parts constitute a well-balanced machine that will stand squarely upon the wires. The springholders keep the parts from reversing till after the new picket is put in.

L represents a board, to which is attached my improved tension device, which consists of the arm M, pivoted at m to said board, and formed with the curved arm N, provided with the curved sloth, which is guided in its movements by the screw or pinion 0, which works in said slot. The arm M is provided with two studs or rollers 1) 17, between which the wires pass, and with the ears q q, in which is held the pin 7', beneath which and beneath the ears the wire is passed. This arm is provided with a suit-able handle 5, by means of which it is operated.

By moving the tension-arm on its pivot the tension upon the wire can be regulated by causing the wire to hold more or less and to pass over more or less surface of tension, as will be readily understood. One of these tension devices will be used for each pair of wires.

\Vhat I claim as new is 1. In a fence-making machine, the combination, with the board I.) and the twisters, of

the rack-bar, its handle provided with the projection, as described, the stop-blocks on the board, and the spring carried by one of said blocks substantially as shown and described, and for the purpose specified.

2. In a fence-making machine, the combination, wit-h the tension-arm M, pivoted near one of its ends and at its other end formed with curved arm slotted as described, of the pin working in said, slot, and the rollers on the arm M, bet ween which the wires pass, substantially as shown and described, and for the purpose specified.

In testimony whereof I atlix my signature in presence of two witnesses.

CHARLES \V. BUSH;
